Scientists Say They've Created A Freaky New Form Of Light

It's easy to shine light through a crystal, but researchers at Princeton University are turning light into crystals--essentially creating "solid light."

"It's something that we have never seen before,"
Dr. Andrew Houck, associate professor of electrical engineering and one
of the researchers, said in a written statement issued by the
university. "This is a new behavior for light."

New behavior is right. For generations, physics students have been taught that photons--the
subatomic particles that make up light--don't interact with each other.
But the researchers were able to make photons interact very strongly.

To
make that happen, the researchers assembled a structure of 100 billion
atoms of superconducting material to create a sort of "artificial atom."
Then they placed the structure near a superconducting wire containing
photons, which--as a result of the strange rules of quantum entanglement--caused the photons to take on some of the characteristics of the artificial atom.

"We have used this blending together of the photons and the atom to
artificially devise strong interactions among the photons," Darius
Sadri, a postdoctoral researcher at the university and another one of
the researchers, said in the statement. "These interactions then lead to
completely new collective behavior for light--akin to the phases of
matter, like liquids and crystals, studied in condensed matter physics."

Pretty complicated stuff for sure. But what exactly is the point of the ongoing research?

One point is to work toward development of exotic materials, including room-temperature superconductors.
Those are hypothetical materials that scientists believe could be used
to create ultrasensitive sensors and computers of unprecedented
speed--and which might even help solve the world's energy problems.

"This
work is not going to lead to a lightsaber," Houck joked in an email to
The Huffington Post, "unless you are speaking of a metaphorical tool
that will cut through our veil of ignorance like a lightsaber through a
tauntaun."
